Comment on YSK that if your turn signal is blinking unusually fast (like 3 or more times a second), it generally means you have a bulb out.

This "hyperflash"ing will also happen if you have replaced an incandescent bulb with an LED bulb due to the different power requirements.
LEDs draw so much less power that they don’t draw enough current through the flasher relay. The relay will then think that the bulb is burned out.
To fix hyper flash due to having installed LED bulbs you can wire a resistor inline or replace the flasher unit with a unit designed for LED bulbs.

Yeah. And that’s why fitting arbitrary bulbs in your car isn’t allowed in some countries. You have to use something that is certified for use in your specific car.

  Yes, there is mandatory inspection every 2 years here. Your car will absolutely fail if you use some uncertified shit.

Blinkers will flash fast with trailer hooked up too if there is a light duty flasher.
